Can I create a smart lighting group without a smart light?

I would like to use a smart lighting motion sensor to trigger a doorbell camera to start recording. Sort of a long distance pre-roll so the Doorbell camera would start recording as cars come up my long driveway instead of when a person walks onto my porch. So, before I start buying an Echo 4th gen (bridge) and a smart lighting motion sensor can I create a smart lighting group without any smart lights just the smart lighting motion sensor?
